Exercising in the Morning May Be Linked to Lower Heart and Metabolic Risk

Researchers analyzed about a year of Fitbit and health data from roughly 14,500 people and reported that those who exercised in the morning had lower rates of cardiometabolic risk factors and a 31% lower reported risk of coronary artery disease.

Researchers analyzed about a year of health information from roughly 14,500 people, including heart rate data collected by Fitbit devices. The study compared participants who exercised in the morning with those who worked out later in the day. Reported differences focused on cardiometabolic risk factors and coronary artery disease. The analysis described associations based on the collected data. Key findings: - The dataset covered about one year and included heart rate records from wearable devices for roughly 14,500 participants. - People who exercised in the morning were reported to have lower rates of cardiometabolic risk factors such as type 2 diabetes, obesity, high blood pressure and high cholesterol. - Morning exercisers were reported to have a 31% lower risk of coronary artery disease compared with those who exercised later in the day. - The results are presented as associations observed in the study data rather than proof of a direct cause-and-effect relationship. Summary: The study reports an association between morning exercise and lower cardiometabolic risk and coronary artery disease in this cohort. Undetermined at this time.
